PREPARATIONS: How to check the voltage setting and set up the balance.
Before the balance is set up for the first time, the operating voltage must be set to conform to the line voltage to which the balance will be connected.
Select a suitable location for your balance; this helps increase operating efficiency.
Install the pan on the balance.
Level the balance and check leveling on a regular basis.
Checking the voltage setting
At the factory, a tag is placed over the power
connector (7); the voltage setting is printed on this
tag.
If the voltage setting printed on the tag does not agree
with the power supply voltage, or if the tag is missing,
the setting of the voltage selector switch (5) on the
rear wall must be checked, and if needed, changed.
Admissible power supply voltages with switch
positions:
115 V: 92 V...132 V
220 V: 184 V...265 V

Location
– Stable location; as free from vibration as
possible.
– Make sure there are no large temperature
fluctuations.
– Avoid a location where there is direct sunlight
or drafts.
– Once location is selected, connect the power
cable.
If no ideal location can be found using the above
criteria, the balance can still provide good results.
This can be achieved by following the instructions
listed under "Integration time setting and stability
detector".
Install pan on balance; level balance
– Install pan (10) on balance; the conical peg is
centering it in the middle of the opening on the
weighing chamber floor.
– Adjust the two leveling screws (4) so that the
bubble in the spirit level (11) is in the middle
of the circle.
Any time the balance location is changed, recheck
the leveling.
